Show.
The vertical core-pulling slide block 10 is installed in outer layer slide body 2 by vertical slipper lead 12, and vertical core pulling is slided
Block 10 can be moved up and down along vertical slipper lead 12；Tiltedly square pulling block is provided with by pulling block pin 11 on vertical core-pulling slide block 10
9, the oblique side upper end of pulling block 9 is installed in the front space groove of central slider 4, thus, central slider 4 can be driven by oblique square pulling block 9
The vertical ganged movement of core-pulling slide block 10.
The front end of central slider 4 is provided with slide guide ball 5, and slide guide ball 5 is by the first spring of ball 7, the bullet of ball second
The jacking of spring 8, to reduce relative rub when ensureing that tiltedly the square upper end hanging platform of pulling block 9 Relative sliding on the front end inclined-plane of central slider 4 is moved
Wipe resistance；Ball second spring 8 is played screw 6 by plug and stoppered with anti-dropout, as shown in Figure 3.
The central slider 4 is installed in the central channel of outer layer slide body 2；During core pulling, core pulling is driven by Angle Pin 1；Outer layer
Slide body 2 is installed on mould template by guide layering 3；The effect of wear-resisting compact heap 13 ensures that outer layer slide body 2, center are slided
The parking position accuracy of block 4, vertical core-pulling slide block 10, as shown in Fig. 2, Fig. 4, Fig. 5, Fig. 6.
The mechanism outer layer slide body 2, central slider 4, the moulding section of vertical core-pulling slide block 10 collectively constitute this core pulling
Mechanism moulding section；During core pulling, the vertical core pulling upwards of vertical core-pulling slide block 10 is driven by the first core pulling of central slider 4, most
Outside core pulling is taken out of by outer layer slide body 2 together eventually；Mechanism can complete secondary side core-pulling and once vertical core-pulling function, such as scheme
7th, shown in Fig. 8.
During real work, as shown in figure 9, its motion operation principle is as follows：
1) after molding, Injection Motor Template pulls mould dynamic model part to retreat, and mould goes out at die joint when opening, Angle Pin 1
Move, moved so as to stir the direction as shown in K2 of central slider 4 first, a shown on central slider 4 by K1 directions shown in Fig. 9
B points motion shown on point outer layers slide body 2；Thus, central slider 4 carries out core pulling action first, with this synchronously, and center is slided
The front end of the core pulling of block 4 will pull on the tiltedly square direction as shown in K3 of pulling block 9 by inclined-plane thereon and move upwards, and tiltedly side's pulling block 9 will
Vertical core-pulling slide block 10 is driven to do vertical core pulling campaign shown in K4, what its motion guide was then provided by vertical slipper lead 12
Vertically-guided K5 directions ensure；Move to after b points are overlapped shown on outer layer slide body 2, hang down after a points shown on central slider 4
The vertical core pulling action of straight core-pulling slide block 10 is completed, and Angle Pin 1 will outwards be taken out together with central slider 4, outer layer slide body 2
Go out, so as to complete outer layer slide body 2, central slider 4, the core_pulling demoulding at formed product position corresponding to vertical core-pulling slide block 10；
2) when resetting, with core pulling action process on the contrary, Angle Pin 1 first pushes back central slider 4, so that by vertical core-pulling slide block 10
Reset is pushed back in advance, then outer layer slide body 2 is pushed back reset by Angle Pin 1, finally by wear-resisting compact heap 13 by outer layer slide body
2nd, central slider 4 pushes back complete reset completely, and mould closure waits the beginning of next injection cycle.
